It eliminates the need to open/cut the module and makes it so much easier to re-use second-hand TCUs! Automatic virgin state preparation – no extra steps required!
This license is developed for easier replacement of faulty 7G-Tronic (VGS4NAG2) Transmission Control Units in Mercedes-Benz passenger vehicles from the FBS4/DAS4 immobilizer generation. All vehicles equipped with 7G-Tronic (VGS4NAG2) TCUs are supported!
The new and improved procedure for adapting used 7G-Tronic VGS4-NAG2 TCUs goes like this:
1. Read the data from the original FBS4 module via OBD or on bench*
2. Write the FBS4 data back to the replacement TCU via OBD and internal CAN-Bus** or bench* connection
